Application led November 1'?, 1920. Serial No. 424,630.

I This invention relates to bottle washing apparatus, and more particularly to apparatus wherein the cleansing liquid or solution is used repeatedly. The object of the inveir tion is to provide such apparatus with an eilicient means for removing from the liquid or solution the labels and other material that may be dislodged from the bottles while the latter' are being subjected to the action of the liquid or solution. Further and more limited objects of the invention will appear hereinafter and will be realized in and through the combination of elements embodied in the claims hereto annexed, the invention being illustrated in the drawings forming part hereof, wherein Fig. 1 repre sents a plan view of a portion of a bottle washing apparatus having my invention applied thereto; Fi 2 a vertical sectional view through such apparatus corresponding substantially to line 2 2 of Fig. 1, one of the jet boxes being shown in section; Fig. 3 a sectional View corresponding` to the line 3-3 of Fig. 2; and Figs. 4, 5 and 6 details in perspective of the label remover.

Bescribing the various parts by reference characters, 1 denotes the side walls and 2 the bottom of the casing through which bottles may be conducted, the bottles 3 being indicated as mounted upon transverse carriers, indicated at 4, the said carriers being preferably connected to form an endless belt device supported upon rails 5 by rollers 6, said rails extending longitudinally through the casing'.

The casing may be provided with a top 7. A pump 8 shown as driven by an electric motor 9 has its inlet connection 10 extending to the adjacent side wall of the casing and communicating with a main tank A in the lower part of the casing and near the bottom thereof, through a. strainer 11. 12 denotes the outlet or delivery connection from the o Jump extending upwardly into the tank and discharging into a jet box 13 having nozzles 1-1 adapted to register with the mouths of the bottles 3 supported in inverted. position upon the carriers. he rails 5 are shown as conveniently supported by brackets 15 secured to the jet box. Above each jet box is a pan or tray 16 having perforations 17 in the bottom thereof, and to which liquid is supplied by a pipe 18 connected with the pump delivery by a pipe 18a. The water in the pan 16 is discharged upon the bottoms and sides of the bottles. By this arrangev` ment, the insides of the bottles are subjected to cleansing and sterlizing liquid supplied from the jets 14 while the outsides of the bottles are subjected to the water delivered thereto from each pan or tray 16. As the bottles advance, through movement of the carriers 4, some of the liquid from the nozzles 14 will impinge upon the outsides of the same, the nozzles thus cooperating` with the liquid supplied from the pan or tray to dislodge t-he labels and other refuse matter from the outsides of the bottles.

The bottle carriers are moved intermittently along the rails, preferably the distance between the adjacent transverse carriers. To

secure this action, the .following mechanism is employed. 19 denotes a rock shaft mounted in the bearings 20 and 21 and on the sides of the tank or casing. At one end, this rock shaft is provided with a crank arm 22. This arm is connected by a link 23 with a crank disk 24: carried on the shaft 25 of a worm gear 26 which is driven by a worm 27 on a shaft 23, the last mentioned shaft being driven from a motor shaft 29 by means of a gear 30 and a pinion 31. Mounted on the shaft 19 is an arm 32 to the lower end of which a pawl 33 is'pivoted. The lower end of this pawl is adapted to engage projections 34 on the carriers, thereby to move the same intermittently.

As stated hereinbefore, it is desirable that the cleansing and sterilizing liquid may be used repeatedly. For this purpose .it is necessary that the labels and other sediment be removed therefrom before the liquid reenters the tank and the pump inlet connection. For the purpose of effecting such removal, I have provided special label separating means. vProjecting from one side of one of the walls 1 of the casing is a supplemental tank, indicated generally at 35 and comprising a rounded bottom wall 36, an outer side wall, and end walls 37. This tank is adapted to receive the liquid supplied by the nozzles 14 and theperforations 17 and in turn to discharge such water, after the removal of the labels and other sediment., back into the main tank or receptacle. The tank 35 communicates with the main tank through a large opening 38 formed in one of the walls 1 in said tank immediately above the plate 39, said plate forming Va cover for the portion of the main tank which contains the liquid. The. liquid received within the tank 35 is in turn discharged into the main tank beneath the cover 39 through a wide opening 40 formed in the adjacent side wall of the main tank and located above the bottom thereof.

Mounted within the auxiliary tank 35 is a tray. This tray comprises sides 41 and a bottom 42. From the outer end of the bottom, there projects upwardly a. short end wall 43, the upper edge of the said wall being corrugated to provide a seat Jfor one end of a perforated corrugated screen plate 44. The inner end et the screen plate 44 is shown as attached to a support formed by one of the horizontal flanges o't a Z-bar 45, the other' horizontal flange of which is attached to the horizontal flange of an angleiron 41l secured to and within the upper portion of each side wall 41. The angleirons 41L also serve as a means for connecting the sides ot the screen plate to the sides 41. The other iange 45 of the Z-bar supports the screen assembly 41-45 upon an englobar 46 located below the opening 38.

The ilange 45L and the joint between the same and the adjacent wall 1 of the main tank are covered by a flap 47, preferably of rubber, extending from the outer edge o the plate 39 across said flange. Projecting upwardly from each end of the wall 43 is a strap 4S. Each strap is provided with an angular strap 49 secured thereto, the upper ends of the straps 48 being connected as by an anglebar 50. Each strap 48 is braced by means of a stay 51, preferably an angleiron, connected at its upper end to its strap or the bar 50 adjacent thereto and at its lower end to the angle-bar 41a. When the screen assembly is in the position shown in full lines in Fig. 2, the horizontal projections of the straps 49 engage the top of the outer wall of the receptacle 35.

vSurrounding the screen assembly 41 45 is a screen comprising a cage having outer and inner vertical walls 52 and 53, a bot tem wall 54 and end walls 55. The upper edge of the inner wall 53 is clamped between the vertical flange of the angle-iron 46 and a plate 56, and these parts are riveted together. lWithin the cage 52-55 is a third screen. The last mentioned screen comprises a vertical wall 57, preferably contacting with t-he wall 52, the upper ends of both walls being conveniently secured to an angleiron 58 extending around the top of the cage 52,55 and serving to support the cage and the screens therein upon an angle iron 59 secured within the outer and sidewalls of the auxiliary tank 35. Thewall 57 is spaced from the delivery end of the screen plate 44 and is curved inwardly beneath such end, as shown at 57a, engaging the bottom screen plate 54 therebeneath. Near its inner end, the bottom 57b is secured to the bottom 54 by a strap 62. The upper end of the wall 53 engages the bottom plate 42. The corner formed between the bottom 54 and side 53 is braced by a small angle-bar 63. Handles 64 are secured to the angle-bar 59 at opposite ends ot the screen assembly whereby the parts 41-63 inclusive may be removed from the auxiliary tank.

Secured to the end of the rock shaft 19 which projects through the wall 1 adjacent the tank 35 is a crank arm 19a. This arm connected by a link 65 with one arm 66 et an angle-lever pivoted upon a stud 67 carried by a bracket (i8 secured to the wall 1 et' the tank. The other arm G9 of said angle-lever is connected by a chain 70 with the angle-iron 50.

T he inner end of the bottom wall of the tray projects through the opening 40 in the side 1 and above a screen 7l that may be conveniently supported by angle irons 7 2, the said screen being of finer mesh than the screen 44 and being of a width which will permit it to be withdrawn through the opening 40 at'tcr the screen assembly 41--45a has been removed.

Nearly all ot the water delivered to the screen 44 passes through the periiorations thereof, and the screen 71 is employed because ot' the facttha-tsome fine sediment or small pieces of softened labels may pass through the openings in the screen 44 with this water and serve to clog the strainer 11. By the use of the screen 71, practically all ot this liner material will be collected, enabling the solution in the tank to be used repeatedly and without clogging the pump strainer.

5l/lith the parts constructed and arranged as described, the. operation will be as tollows: Cleansing liquid is supplied from the tank beneath the plate 39'to the pump S and thence to the jet box 13 and through the nozzles 14 to the interiors and exteriors ot' the bottles 3 on the carrier 4. At the same time, water will be supplied by the pump through the pipes 1.8-18a to the pan or tray 16 and thence upon the exterior of such bottles. This water will drain from the plate 39 and opening 3S upon the screen plate 44. The arrangement of the various screening surfaces will permit the water to.

be delivered into the tank 1, the labels being iinally collected by the wall However, there is danger that when the screen 44 is short, or the angle of inclination is less than about 150, the labels will adhere to the surfaces over which they pass, with the result that they will be reduced to a fine, pulpy condition before reaching the wall and the screen 71, and suiiicient of this pulp will be delivered into the main tank to cause a clogging of the pump strainer 11. To prevent this action, the screen assembly 41-45a is arranged to be rocked upon the flange 46.V This rocking may be pro duced by the rock shaft 19 which, as pointec out hereinbefore, serves to move the bottle carriers intermittently along the rails 5. The rocking of this shaft, through the parts 19n and Sti-70, 4will raise and lower the outer end of the screen assembly lil-lfK Thiswill cause the liquid to fiow alternately slowly and swiftly over the screen plate 4st, allowing the major portion of the liquid to pass through the screen plate when the latter is elevated and to pass swiftly over the plate when 'the latter is depressed and then .to sweep the labels and sediment from the screen plate and deliver the saine upon the screen surfaces 57, 57at and 571. l/Vhen the labels have accumulated, the com- Vplete assembly, comprising the parts il--fi3,

may be lifted from the auxiliary tank and the labels removed. lVhen there is sufficient room to accommodate a long screen 4:4, inclined at an angle of' about 15o or greater, it will not be necessary to rock the said screen in order to sweepl the labels off the same and permit the greater portion of the liquid discharged thereupon to be strained through the perforations thereof and be delivered to the screen 7l.
